This line of conjecture raises another tantalizing possibility. What if Meshullam son of Zerubbabel is not the author but only the subject of Second Isaiah? In fact, “Isaiah” is a fairly rare name in the Bible, borne by approximately seven individuals. One of these is a member of the post-Exilic house of David and the nephew of our Meshullam (1 Chronicles 3:21). Is it conceivable that the misattribution of chapters 40–66 to Isaiah of Jerusalem was just an innocent mistake—for both were written by men named “Isaiah?”
